GINNING AND CLEANING T /IACI-IINE.

Application filed December 29, 1915, Serial No. 89,142.

1 0 all who-m it may concern Be it known that l, lVILLmM D. MoCoY, a citizen of the United States of America, residing at rs'rooklyn, N. Y, have invented a new and useful Ginning and Cleaning Mach" e, of which the following is a specification.

lily invention relates to the ginning of material such as cotton and the general objects of my invention are to produce a. machine of simple, compact and inexpensive construction for the ginning of cotton and similar materials which will operate rapidly and effectively and which will gin the short and the longstaple cotton without injuring the fibres and without breaking the seeds.

Other objects are to avoid waste of lint through incomplete ginning and to secure a finished product which Will sample to the highest possible grade.

In the accomplishment of the foregoing and other objects I employ a grid or ginning wall made up of closely spaced, relatively small rods and a wiper of frictional material held in yielding engagement with said grid, relative motion being imparted to the grid and wiper in a direction transverse to the rods of the grid so as to cause the fibres protruding through the grid tobe caught and pulled through by the Wiper. According to the preferred construction the grid, or gin niug wall, is in the form of a. cylinder and a plurality of the wipers engage with the inner surface of this ginning wall.

The fibres are preferably started through the interstices in the ginning wall by a current of induced air and this same flow of air is usually relied upon to carry off the lint to a bin or other receptacle.

Various other features and details of construction will appear as the specification proceeds, attention being directed to the accompanying drawings illustrating the iir vention embodied in a practical and'preferred form.

In these drawings Fig. 1, is a view partly in vertical section and partly in side elevation of the machine constructed in accordance with and embody- Renewed March 22, 1921. Serial No. 454,417.

ing the invention, the section being taken substantially on the plane of the line 1-1 of Fig. 3.

Fig. 2, is a perspective view of the ginning cylinder illustrating its method of construction.

Fig. 3, is a part sectional View taken at the left hand end of the machine illustrated in Fig. 1.

Fig. l, is a fragmentary sectional view taken at the opposite side of the hopper in Fig. 1.

Fig. 5, is a detail detached view of one of tee wip r pads and its spring support.

In the machine herein illustrated, both the ginning cylinder and the wiper blades are mounted on a single supporting shaft 7 which serves both as a support and as a means for rotating oneof these members in respect to the other member.

The construction of the grid or ginning cylinder will be best understood by reference to F 2 wherein the same is shown as made up of a hub 9 supporting radiating arms 10 which carry a ring 11, this ring having secured therein a plurality of closely spaced relatively small round rods 12. These rods, it will be clear, provide between them a plurality of interstices or ginning openings 13 having, on account of the rounded shape of the rods, tapering inlets on one side and flaring outlets on the other side, this shape facilitating passage of the fibres and air therethrough. A second ring 14 is preferably engaged with the ends of the grid bars or rods 12 thus constituting the whole an opened ended cylinder supported on the shaft 7 by the hub 9 at one end thereof.

The wipers consist in the present embodiment of pads, blocks or strips 15 of rubber composition or other somewhat resilient ma terial possessing the necessary frictional qualities, carried by spring arms 16 secured to a hub 17 supported on the end of the shaft 7 and projecting within the open end of the ginning cylinder.

The spring supporting arms 16 illustrated are of novel construction consisting of two plates of spring metal, the upper one having qr ML team are carried by the casing and thus induce a peculiarly advantageous action of the baffles on the seed, which action is quite independ ent of the lifting of the baffles by means of the members and 55.

The seeds and foreign matter may be carried off by suitable means such as the screw conveyor illustrated at in Fig. 1 working in a trough 61 disposed beneath the reticulated wall of the hopper so as to receive the seeds, etc., therefron The baffle fingers are preferably yielding in character, as by making them of spring wire, so as to yield under the impact of the seeds and so prevent breaking or injuring the seeds. These baliies also are preferably located in the plane of a wiper at the opposite side of the grid so as to act upon the seeds at one side of the grid while the fibres of the seeds are being acted upon at the op posite side of the grid. The result of this is that the seeds are shifted sideways or longitudinally of the grid rods by their on gagement with the inclined baffle fingers and the fibres eing held at this time by the wipers, a more effective separation of the fibres from the seed is effected.

The current of inflowing air passing through the grid clears the wipers of the fibres which they have separated from the seeds, the air thus performing the double function of introducing the fibres in through the interstices in the grid and then carrying off the ginned cotton laterally away from the ginning mechanism. This conducting or carrying ofi' effect is enhanced by admitting a certain amount of free air at the outer end of the ginning cylinder. Thus in the machine illustrated air is admitted at the outer end of the cylinder through a plurality of openings d7. These currents of air constitute carrying currents for floating off the ginned cotton and flowing longitudinally of the wiper pads they serve to draw the fibres off the ends of the wiper pads as fast as separation from the seed is accomplished. The circulating air currents therefore serve to keep the wipers free of loose fibres and prevent any accumulation thereof. The air has the further effect of keeping the parts cool, this cooling function being facilitated by reason of the relatively small size of the rods and wipers.

The annular hopper which surrounds the ginning cylinder confines the material to the extent of preventing the escape of the incompletely ginned seed, the agitation imparted to said hopper shaking up the unginned seed so as to cause the same to be caught by the inflowing air currents and carried into engagement with the ginning cylinder. This agitation also prevents matting of the material. The openings in the reticulated wall 27 are of a size to just pass the completely ginned seeds.

Attention is also directed to the advantage of mounting the Wiper pads on yielding spring arms, these arms taking up the wear of the pads and serving to always preserve a proper engagement of the pads with the grid.

Another important feature of my invention is that in the relative movement of the ginning cylinder and wipers the fibres will be engaged by successive wipers, an easy and gradual separation being thereby accomplished without breaking or injuringthe fibres.
